| Abstract: | Summary The increased downward mobility of phorate, quinalphos and carbofuran residues was detected in soil with increase in depth
of soil column whereas aldicarb was found to remain localised mainly in 0–7.5 cm and 7.5–15.0 cm layers. Persistence of organophosphate
insecticides was higher as compared to carbamates in all the soil layers. Residues of all the four insecticides got distributed
in all parts of okra plant through uptake but accumulated in higher amounts in fruits only.
